Unless you believe that Japanese version makes trees mutate, it's still pollarding.

The japanese version depends on propogating a specific mutated variant.

Yes. It's exactly like how it works everywhere, though? You can't pollard any tree, it needs to have genetically predetermined ability to sprout from the stump.

Isn't this just Pollarding and/or Coppicing, which have been practiced for at least 2000 years in Europe (and probably many other cultures as well), with a healthy dose of orientalism added on top?

Are coppicing and pollarding used at all to produce timber? I had the impression that it was done only to make firewood, and was cut repeatedly without letting it grow like described in the article.

It depends of the type of tree. Ash used to be used both for firewood and timber in France. I have ~35 250 year old ash trees like this, a good chunk of the branches are straight, just not as vertical as the ones from the technique above (which looks really neat). Those have not being well cared for by the previous owners though, I'm quite sure that with better care and selection of buds they would have produced more straight branches.

Im confused.. wouldnt this be suspect to a weight limit - as the full stem would weigh on the carrying "tree" - especially during wind and storms?

When doing coppicing it's definitely something to be careful with. Once started, the trees needs to be cared for regularly. E.g. on the ash trees I have, it needs to be "harvested" every 8 to 9 years. If you fail to do that there's the risk of the tree splitting because of the weight but also branches breaking indeed in case of storms.

It's not limited to Japan. The French call them 'trognes' https://www.agroforesterie.fr/la-trogne-arbre-paysan-aux-mil... Other countries do it too : https://trognes.fr/trognes/trognes-a-travers-le-monde/

In english this is called pollarding a tree. Historically it has been used for smaller wood pieces (firewood, etc). It's fuctionally different [from daisugi] because you don't get construction grade timber from it

If it makes you feel any better, the reverse holds as well. Grass is greener mentality exists everywhere.

I remember in the 1990s watching a bit of British TV, where an ad asked, "What do women in Los Angeles know about beauty that British women don't?" (obviously selling some "secret" "American" product).

In LA those are either French or Italian women, selfishly hoarding all the good skin cream. I then wondered who the French and Italian women think are the beauty-secret-holders...

Few trees called "cedar" are in the Cedrus genus. To be fair many of these were called a type of "cedar" before the Cedrus genus was even coined. Cedar really just means "a really good tree" (for woodworking)

TIL that PNW Western Red Cedars are not in fact, Cedar trees!

Again, what is and isn't a "true cedar" is a silly debate. Some of these trees were called cedars before Cedrus was even coined. Junipers and even citrus were called cedars long before Linnaeus came along. It really got applied to any tree that had scented, rot-resistant wood

In fact, most trees called cedars are NOT Cedrus.

It's cute because it's trees. Somehow I keep thinking Mad Max where women were kept just to produce baby and milk, or Alien where alien "subtree" sprouted from human "tree". I guess nature/human is cruel?

Yeah I kinda feel bad for the trees but they probably don't care

Please link a photo of a coppice/pollard in Europe that's as straight as this, along with the location where I can see it. If you do, I have got a great new travel destination. If you don't then everyone else (and hopefully you too) will understand why people think this is special enough to link beyond the fact that it happens to be in Japan.

The parent commenter rightfully criticizes these kinds of sentences: > Necessity being the mother of invention, this led to the creation of an ingenious solution: daisugi, the growing of additional trees, in effect, out of existing trees — creating, in other words, a kind of giant bonsai. It tries to sell something as completely unique. It’s not. For example this sentence should emphasize what’s unique with daisugi,…

> there is a very good English word with this exact same meaning as written in this sentence: grafting.

Grafting is joining cuttings from one tree to a rootstock of another. That is not what's going on here at all, it's limited to a single tree.

Something like "selective pollarding", maybe, but that's very far from being a common English word. And as I said, most pollarding I have seen is nowhere as straight and tall as this.

This article is just a rehash or summary. Check out one of the sources it links to (since the other is broken) for details on the technique: https://mymodernmet.com/kitayama-cedar-daisugi/ The strength & flexibility I would guess are attributable to the lack of knots and the straightness of the grain. One thing both writers keep doing that's annoying is calling it a cedar. The tree is cryptomeria japonica , known as…

Few trees called "cedar" are in the Cedrus genus. To be fair many of these were called a type of "cedar" before the Cedrus genus was even coined. Cedar really just means "a really good tree" (for woodworking)

I'm not caring so much about the Cedrus genus, as the dilution of the word through unimaginative overuse and over-application. But to the extent that it still means anything at all, I would say it means an aromatic evergreen, since those are the two traits that seem to unite all the various trees colloquially referred to as cedars.
